In pediatric neurosurgical practice, it is often beneficial to measure intracranial pressure (ICP) in deciding the operative indication, observation of the postoperative course, or assessing the prognosis. Honda et al. developed a transducer (F.P. sensor), which is easy to use, sensitive, and highly accurate in measurement of ICP from the anterior fontanelle. The authors have developed a new method for fixation of this measuring device on the scalp.
The apparatus comprises two main parts, the guide ring, which has three notches for fixation, and flanged springs, which are connected to the transducer on the scalp by means of adhesive. Each part of the apparatus can be easily connected or disconnected in one action. For adhesive, alphacyanoacrylate appeared to be most suitable because of its strength of adhesion, negligible reaction on the skin, and the rapidity of reaction. However, it is quite difficult to remove the device from the skin after the measurement. To overcome this problem, acetone, which is a solvent of alpha-cyanoacrylate, is applied to the guide ring. Alpha-cyanoacrylate exerts a considerable holding strength on the skin, but repeat application of acetone will allow painless guide ring removal.
